After announcing a Rs 2.11 lakh crore recapitalisation plan this year, the Finance Minister on Thursday spelt out a banking road map to improve the functioning of public sector banks. The new set of guidelines, the finance ministry said, will stress on rigorous due diligence, post-sanction follow-up on loans and separate asset management verticals to ensure public savings are untouched. As part of the plan, the Centre will infuse Rs 88,139 crore -- of which Rs 8,139 crore is through budgetary allocation -- into the banks by issuing recapitalisation bonds this financial year. IDBI Bank will corner most of this money at Rs 10,610 crore.
